Công nghệ kiểm soát cát sử dụng sỏi chèn là phương pháp đáng tin cậy, hiệu quả và vẫn đang sử dụng rộng rãi trên thế giới. Yếu tố quan trọng quyết định thành công trong phương pháp này là việc lựa chọn kích thước sỏi chèn phù hợp với tính chất hóa lý và kích thước hạt mịn của tầng khai thác cũng như phương pháp thi công phù hợp. Đối với từng điều kiện mỏ khác nhau, việc lựa chọn loại sỏi chèn và phương pháp thi công chèn sỏi gặp nhiều khó khăn và là thách thức lớn đối với các kỹ sư và các nhà quản lý. | 48 Journal of Mining and Earth Sciences Vol. 62 Issue 3a 2021 48 - 56 Study for gravel slection and pack operation for oil production well on Song Doc oil field Quan Anh Tran 1 An Hai Nguyen 1 Vinh The Nguyen 2 Hung Tien Nguyen 2 1 PetroVietnam Exploration and Production Corperation Vietnam 2 Faculty of Oil and Gas Hanoi University of Mining and Geology Vietnam ARTICLE INFO ABSTRACT Article history Sand control by gravel packing is by far the most reliable and effective Received 07th Feb. 2021 sand control method and is being used worldwide. One of the most Accepted 26th May 2021 important factor for successful operation is gravel size selection which is Available online 10th July 2021 suitable with properties of well and particle size of sand from the Keywords reservoir also the operation method needs to be considered during study. Gravel packing Due to the variety of different oilfield the selections of gravel size and operation method are challenges for petroleum engineer and manager. Sand control Oil production wells in Song Doc oil field are producing in Miocene and Song Doc oil field. Oligocene with very high rate of sand production some of the wells were plugged by sand. Therefore the study on the selections of gravel size and operation method is needed and important. In this study theory analyzing was used in order to yield advantage and disadvantage of each gravel packing method and their operation. Based on the operating condition on Song Doc field and the availability of equipment on site gravel packing method by thru-tubing with vent screen was selected. The coil tubing was chosen as the operation method. This is the best sand control method for the Song Doc oil field with low cost and high effectiveness sand control.
